Surface circulation in the oceans

Definition

Wind-induced circulation in the atmosphere generates five major vortices: two in the Pacific, two in the Atlantic, and one in the Indian Ocean.

As anticipated by Coriolis law these rotate in the northern hemisphere in the negative direction (clockwise) and positive in the southern hemisphere (counterclockwise) ).

They are classified as cold and hot according to the temperature they are acquiring in the equatorial and polar zones.

Circulation by dome formation

Isobaric plane inclination

Note

If the depth varies with horizontal position, it creates a pressure difference that contributes to the displacement of water.

Depth Difference Generation

Quote

The experiment conducted by Stommel, Arons, and Faller demonstrated how a source and the Coriolis force created imbalances and pressure differences to displace water without the involvement of wind.

In this case, we have a rotating system, experiencing centrifugal acceleration, and a liquid source that alters the quantity at a point near the origin:

The experiment conducted by Stommel, Arons, and Faller demonstrated how a source and the Coriolis force created imbalances and pressure differences to displace water without the involvement of wind.

In this case, we have a rotating system, experiencing centrifugal acceleration, and a liquid source that alters the quantity at a point near the origin:

Injecting fluid at the source position creates a level D_0 at that location. Additionally, the rotation generates centrifugal acceleration that accumulates the liquid at a point with a larger radius r. Therefore, the depth can be calculated using list as follows:

equation

Since hydrostatic pressure is dependent on depth, we can express it with list=4250 as:

equation=4250



The pressure in a rotating system can be calculated using list and is given by:
